AERIAL BOMB.

Specification of Letters Patent.

' Patented Mar. 15, 1921.

Application filed July 6, 1920. Serial No.s94,174.

useful Improvements in Aerial Bombs and I do hereby declare the following to be a.

full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appcrtains to make and use the'same.

lhis invention relates to new and useful improvements in explosive bombs and particularly to bombs which are to be dropped One object of the invention is to provide a device of this character which has novel means for insuring the explosion of the priming cap, when the bomb strikes the objective.

Another object is to provide a tube in which the priming cap is located, and which has a plurality of openings to permit the fire from the cap to readily reach the explosive within the shell of the bomb, and thus insure the proper explosion of the said explosive. I 7

Other objects and advantages will be apparent from the following description when taken in connection with the accompanying drawing. 7

In the drawing:

Figure 1 is an elevation of a bomb made in accordance with-the invention.

Fig. 2 is a longitudinal central sectional View through the bomb. 1 V

Fig. 3 is a horizontal transverse sectional view through the bomb, on the line of Fig. 2.

Referring particularly to the accompanying drawing, 10 represents the shell of the bomb which is formed from suitable metal and having the lower thickened and pointed nose 11, adapted to strike an objective. The upper end of the shell is open, and is externally as well as internally threaded in the said opening or mouth. Engaged in the mouth of the shell, and removably secured therein by the threads, is a closure cap 12,

while a hollow arched cap 13 is engaged with the external threads, and covers the closure 12. V

Disposed longitudinally through the center of the interior of the shell is a small tube 14, and slidable longitudinally in this tube is the firing pin or plunger 15. The

lower end of the tube is seated over a central recess formedin the inner wall of the nose of the shell, and said lower end of the tube is flared outwardly, as shown at 14, and is formed with a series of perforations 16. Seated in the recess 17, within the lower end of the tube 14, is the priming cap 18, the flame from which is adapted to pass out through said perforations, and ignite the ex plosive 19, which is disposed within the shell, around the tube 14. The upper end of the pin or plunger 15 extends through the center of the closure 12, and carries on.

its upper end, which is disposed within the cap 13, a we1ght 20. A coil spring 21 is engaged around the upper .end of the pin 15, between the closure 12, and the lower face of the weight, to hold the weight in elevated position, and the lower end of the pin out of Contact with the priming fuse.

Secured to the upper side of the cap 13 is a set of guiding fins or wings 22, which vinsure the proper and straight downward flight of the bomb when dropped from an aerial vessel.

When the bomb is dropped from a height, and the nose strikes an object the suddenf checking of the flight of the bomb will cause the weight 20 to move downwardly against the tension of the spring 21, and drive-the lower end of the firing pin 15 into the priming cap 18, with the result that the fire from said cap will pass out through the perforations of the tube14, and ignite the explosive withinthe shell. The shell will then burst, with great force, and cause destruction to surrounding objects.

The spring 21 is of sufficient strength to withstand ordinary jars and shocks incident to handling the bomb, and will only cause the firing of the priming pin when subjected to extraordinary shocks and jars,

as when dropped froma great height.

7 The plunger or pin 15 fits snugly, but readily slidable'within the tube 14, so that the striking of its lower end, against the priming cap, will be assured.

'VVhat is claimed is:

An aerial bomb including a shellfor containing an explosive, a longitudinal central tube in the shell and having its lower end flared and formed with a plurality of flame openings, the internal face of the lower wall of the shell having a central recess in which is disposed a fuse cap and over which the j lower end of said tube is secured, a closure in the upper end of the shell, firing plunger pin slidable longitudinzilly in the central tube and extending upwardlythrough the closure, in covering ca-p engaged on the 5 upper end of the shell, a guiding tail car- In testimony whereof, I aflix my signature, in the presence of two Witnesses.
